Input: Consider Input: Article: A lot of people these days believe Valentine's Day is a made-up holiday designed to promote the sale of greeting cards and gifts. And while there may be some Arguments for that, there is a mysterious story as to why February 14th has become known today as "Valentine's Day." Our story dates back centuries ago, to the Roman Empire, and the martyrdom   of two or three Christians named Valentine. At least one of those Valentines is thought to have been killed on February 14th. Legend has it that this particular Valentine wais killed by a Roman emperor because he secretly presided   over the marriages of young men and women, against the wishes of the Emperor, who wanted only single men to fight in his army. However, there is no historical evidence to back this up. But what is widely known is that the love-element to Valentine's Day can be first traced   to the poetry of Geoffrey Chaucer. Chaucer wrote a poem in 1382 to mark the anniversary of his King's engagement, and scribed a line -- "For this was Saint Valentine's Day, when every bird cometh there to choose his male." From this point, on Valentine's Day became intertwined with love. But for the pessimists out there who see Valentine's Day as a commercial idea, there is some historical evidence to back this up as well! The true popularization   of Valentine's Day can be traced to late 18th century England, when a British publishing company first started selling paper Valentine's Day cards with tender words on them. They became so popular that by the middle of the 19th century, some 1.3 billion British pounds a year were being spent on Valentine's Day gifts.

Input: Consider Input: Article: Howard Dill is a giant among giant pumpkin  growers. He grew world champion pumpkins for four years running,from 1979 to 1982, and missed winning the fifth year by only 5 pounds. Today, his Dill Atlantic Giant seeds are sold worldwide to more than 50 seed companies. The pumpkins grown from his Dill Atlantic Giant seeds commonly weigh in at over 1,000 pounds. "I don't have any training in genetics ; it was all trial and error," Dill says. He got his love of pumpkins from his father and has enjoyed growing them for years. Dill still grows giant pumpkins, but not for competition. In the fall, visitors come to enjoy the pumpkins on his 90-acre farm in Nova Scotia, Canada. He plants ten acres of pumpkins for Halloween and two acres of giant pumpkins. One of giant pumpkins was recently baked into 442 pumpkin pies and sold at $5 each for charity. It you want to try growing a giant pumpkin, Dill recommends starting with a soil test and then adding fertilizer  as needed. Plant the giant pumpkin seed. A giant pumpkin can gain 15 to 20 pounds a day, so careful watering--every day or two--is necessary. You should wait about 130 days until the pumpkin matures and then you can harvest it. Dill's favorite pumpkin set the Guinness Book record in 1981. It weighted 493.5 pounds. "I've grown them larger since, but that one meant a lot," he remembers. "I never would have imagined ten years ago that there would be a 1,000-pounder, but there are many of them now," says Dill. The 2006 world record holder is Larry Checkon of Pennsylvania. He grew a 1,469 pounder. Dill says, "These world champions are grown from my seeds, so I feel like a winner right along with them."

Input: Consider Input: Article: Are you a media addict who would go mad after two hours without TV, friend requests, exciting online games and your mobile - or would you easily survive? Recently, university students around the world were asked to volunteer in a global experiment called Unplugged. It was designed to see how young people would react if they were asked to observe a total media ban by unplugging all forms of media devices for 24 hours. Unplugged is being run by Dr Roman Gerodimos, a lecturer in Communication and Journalism at Bournemouth University. The experiment is now over but he doesn't yet know the full findings. However, during the experiment, Dr Gerodimos said there were already signs of how much the exercise affected volunteers. He said: "They're reporting withdrawal symptoms , overeating, feeling nervous, isolated and disconnected." During their 24-hour painful experience, three of the experiment's guinea pigs had to endure one intrusion  from the media: a BBC reporter plus cameraman who followed them around for the day. They were asked to write down 100 lines about their day offline, but of course, they all waited until the next day when they had access to their laptops. Elliot Day wrote: "Today, my whole morning routine was thrown up into the air. Despite being aware of the social importance of the media, I was surprised by how empty my life felt without the radio or newspapers." From Caroline Scott, we read: "I didn't expect it, but being prevented from the media for 24 hours resulted in my day-to-day activities becoming so much harder to carry out than usual... I didn't break out in a cold sweat like our lecturer expected us all to, but it's not something I would like to do again!" And Charlotte Gay wrote: "I have to say the most difficult item for me to be without has been my mobile; not only is it a social tool, it's my main access point of communication." Earlier in the year, a UK government study found that in the UK we spend about half our waking hours using the media, often plugged into several things at once. And a recent study by Nielson found that on average, US teenagers send and receive over 3,000 texts per month ---that's about six texts per waking hour. So, with technology continuing to develop at an alarming rate, how much time will you set aside for sleep in the future? 
 Question: About Dr. Roman Gerodimos' experiment, we know that   _  . 
 Options: (A) volunteers felt uncomfortable in it. (B) volunteers didn't want to eat anything. (C) the experiment was still going on. (D) volunteers were allowed to take their laptops. 
 Asnwer: A
